A telemetry unit in a weather balloon draws a constant current of 0.015 A from a 12.0 V power supply.
Calculate the electrical energy transferred to the unit during a flight period of 25 minutes25\text{ minutes}25 minutes.
Use the equation:
E=I×V×t E = I \times V \times t E=I×V×t31 exam-style questions on Edexcel GCSE Physics 10.3 Electrical energy and power. Each one has a worked solution and a mark scheme showing where the marks go.
